Can I find experimental data for the decay of Iodine-131?

In summary: Someone has measured the lifetime, and there was probably more than one measurement. Just look for references to those papers to find experimental data.

I'm currently undergoing an assignment in maths were it is is necessary to apply mathematical concepts to aspects in reality. Hence, I have chosen to model the radioactive decay of iodine 131, however I am required to plot the data of the radioactive decay of iodine 131, in order to find the equation rather than using the half-life. Is it possible to find experimental data for its decay.

I intend to find the equation of the function by graphing the data in order to get a negative exponential function.

If it helps my assignment is relevant to radioactive materials (iodine 131) leaked in the Fukushima Daiichi nuclear disaster.

Anything would be greatly appreciated

Thanks

What do you mean by "find the equation"?

I doubt anyone collected a large sample of I-131 and then watched it decaying for months. That would be quite pointless.

There are publications measuring the half-life, did you search those?

Much appreciated

What is that website in case I need data for other radioactive material.

Er... I found it using Google!

Here is a directory of similar data sheets from the same website.

Those tables look like computed values, not measurements.

Is it difficult to find measurements?
